While I don’t necessarily agree with the methods, the reasoning is sound—it’s not a matter of property, but a matter of life. The life in this case happens to be non-human, but it is life nonetheless. Just because nobody actually owns the whales, doesn’t mean they shouldn’t be defended (perhaps, defended from being owned).

On the other hand, whether or not it’s appropriate to take life to defend life seems questionable. Sinking or damaging whaling ships is one thing, but taking lives is another.

I find it hard to believe that eco-terrorism will earn the environmental movement anything but more bad press.
